I am entertaining the thought of a .223 rifle and looking primarily at the savage, 9 twist seems to be the standard offering and I would prefer a 7 twist. What could I expect to get out of a factory savage 9 twist barrel or should I keep looking for a donor action and get a 7 twist CBI from Northland. I would like to get to a grand in the standard 223 and not an AI chamber. I have seen firsthand that the round is capable even with lighter bullets but the results were still in a tight twisted barrel. Long and short of it is this, can I get to a 1000 with hand loads fired from a 1-9" twist with bullets in the 70g range or less?
